PRODUCT DATA

KOST® USA Anti-Wear Hydraulic Fluids

KOST USA Anti-Wear Hydraulic Fluids are recommended for mobile and industrial hydraulic systems where anti-wear hydraulic fluids are specified. They also provide excellent performance in machine tools, servo controls, metalworking equipment, bearings and some air compressor applications.

KOST USA Anti-Wear Hydraulic Fluids incorporate highly effective zinc anti-wear chemistry with premium base stocks. They provide excellent wear control and are fully fortified against corrosion, oxidation and foaming. They control water contamination by an added demulsifier that rapidly separates water so it can be drawn off.

Do not use these oils in ammonia compressors, as a heat transfer oil, with silver bearings, or at prolonged temperatures above 200°F.
